Cane Creek has the ST and LT Thudbuster seat posts that have been reviewed many times here on EBR.
The LT travels quite a bit and even the ST model has 50mm of travel - great for trail and rough riding I'm sure. For my road riding I wanted something for the long rides and when the pavement gets rough, but not too much travel as I enjoy the 'fit' my road ebikes have now....
I have ordered recently the Cane Creek Thudbuster eeSilk to give a try:
These posts make great enhancements to endurance road bikes by reducing the chatter transmitted from the surface to the rider and can be tuned to rider weight through a simple elastomer change. #5 elastomer comes pre-installed, other weight elastomers sold separately. This is a legacy product...

20mm of travel, just enough to take the edge off the road riding I do, is what I hope for without impacting the fit and positioning of the seat too much. Ordered from Cane Creek so I could be sure to get the #9 elastomer rated for the 250lb+ riders (comes with a 3, 5 and 7 elastomer for lower weight ranges) which I'm still in for another 23lbs. ;-)
Bigal1463 - The #3 elastomer included in the package is rated for 100-160lbs for your notes.
Important note - not cheap - $290 USD for the post and first 3 elastomer's and $13 for an extra elastomer if needed, plus shipping. With my goal to ride 5,000kms+ every year I figure this is a good investment in my riding comfort.
I will report back in a few weeks when I have received it and had a chance to ride it a few times.
Cheers
